This doesn't make any sense to me, the refence is near the end, but I have provided the entire question for context. This is an article on metabolomics, an interview with a proinent scientist in the field.

PS - If señal meant patient, this would make perfect sense. My one doubt is if this is some kind of Spellchecker mistake, mostly because I really want it to be "patient", because then everything falls neatly into place.

Explanation:I don't know anything about metabolomics, but signal processing seems to form part of it:

http://en.wikipedia.org/wiki/Metabolomics
Metabolome refers to the complete set of small-molecule metabolites (such as metabolic intermediates, hormones and other signaling molecules, and secondary metabolites) to be found within a biological sample, such as a single organism

Without knowing exactly what apparatus is being used it is hard to say definitively if just "signalling" is okay (as you the asker assume after Emma Goldsmith's answer). I am a physical chemist (or at least I was) and I'm not 100 % convinced that the interview response is talking about MRI as 'ispanix' suggests. If it is MRI then "signal processing" is the definite answer. It would be good to know if the rest of the interview discusses "signalling" - biological marking of foods/drugs so that they can be followed in the metabolic break down.....

Asker: Actually, I think I may see the answer in your first reference, i.e. just signalling. It is referring to biomarkers that indicate predisposition to an illness or condition. I am not 100% sure, but it does make sense.
